Progress Thread Progress Thread- From6to8's 1994 Cobra Supercharger install

[from6to8]

Yes per the instructions the FMU goes to the vacuum tree B/R port.

@from6to8 good idea on wrapping the line that’s something I could do too.

What size injectors are you running again? And @Noobz347 so I have 42's that's for my 95's 331 build but I might actually run an S/C as well with the 331.

About to do some research on 42's with a S/C because I know I've read where some guys have ran them. I'll expect around 340-350 N/A with the 331 and with the blower maybe around 475-500. I'd rather run the 42's with the 94's S/C setup since the expected hp will be around 415's or so.

Thoughts?

Stock 19#’rs for now.

I think I read where some people actually ran the stock ones with a blower. So I should be fine with the 42s but I'm going to do a little more reset when I get back to work

Its only fine because 1. i'm running a FMU which ups the pressure to the injectors, kind of like 'overdriving' the injectors and 2. i'm just running minimal boost anyways.

If i add more MODs (heads/cam/intake, power pipe, MAF, TB, etc) my current setup wouldn't work.

Oh yeah that's right I forgot that's how and what the FM do, makes sense LOL

They work for me.


More folks are about running larger injectors these days but there are more choices too.

It wasn't that long ago that running 60+ lb injectors required a high impedance driver.

gotcha, gotcha.

If you have 42s. I would run them.

I [highly] doubt that your combo is going to need more than that and I only say that because I know my combo is "close" at the very top.

makes sense to me definitely lol. What are you making at the wheels again?

 

[Noobz347]

460/480 at the wheel.

It's been a while but I [do] recall putting a notch or two in the Boost-A-Pump to bring the duty cycle [down] on the dyno.

That parts themselves though, are up to the task at your predicted power level. No problem.

cool all good.

Now I have to research rather a bypass valve comes with the UPR boostmaster pipe as in a thread from 2011 someone said it didn't. If if doesn't, I gotta see about getting one I guess lol

 

[from6to8]

well looks like you the S/C kit comes with the bypass valve so I should be good

 

[from6to8]

@Noobz347 @AeroCoupe ect, what have you learned or read about using an electric boost/vac gauge? I love the price and looks of the Glow shift digital but they only have a digital gauge in electric. Still reading up on what folks think and actually talking to a rep at glow shift he said the electric one should actually be more accurate.

 

[Noobz347]

I've seen them before but I've not owned one.

I'm the guy that looks for analog gauges.

I cannot confirm or deny the seller's accuracy claims however, when you're actively driving you're only looking for things to 'act' correctly.

After that, it becomes a matter of what you like the look of.

 

[AeroCoupe]

If I was going to get one it would be with a stepper motor. Just more accurate.

@Noobz347 and @AeroCoupe looking at meters I'm going to have to go with an SCT BA 2600 90 mm because the Pro M's it seems well LMR definitely doesn't carry them and even folks on fb were talking about how hard it is to get a hold of Pro M. I even had Beekcake racing reach out to them and they weren't able. So I will just go with the Sct and my question is, since I'm getting a tune would any sct ba 2600 for any vehicle lets say a lightning or even if it was one for the 03-04 Cobra, would it work for my application?

 

[Noobz347]

Yes. So long as you have a good transfer function to go along with it.

You do not need a meter that calibrated to any particular ECU or injector if you are digitally tuning.

Make sure you are getting a meter that is the correct: Inlet side MAF or outlet side MAF depending on your setup. I believe the Procharger kit uses an inlet side MAF and not a blow-through.

 

[AeroCoupe]

Just get a 90mm Lighting MAF. Go on car-part.com and buy a couple so you have a spare. A good tuner will already have that transfer function and the OEM stuff is super accurate.

Any particular year range lightning?
